A cold front entered far northwest Oklahoma late in the day, with a dry line extending south into the Texas panhandle. Triple digit heat existed ahead of these two features, with dew point depressions of 30 to 40 degrees Fahrenheit. Convergence along the boundaries combined with the intense afternoon heat allowed for isolated thunderstorms to develop. With steep lapse rates in place, strong downburst winds were the main threat, with large hail a lesser threat. Winds in excess of 60 mph were reported over parts of western Oklahoma, causing some minor damage near Tipton in Tillman county. As this thunderstorms rapidly weakened, a strong heat burst occurred north and west of Altus, with wind gusts over 60 mph, and a peak wind gust of 77 mph.
